Development Of Guided-Inquiry Based Biology Learning Device In A Setting Of Cooperative Learning Model Type Stad

Abstract

The research aims to produce a guided inquiry based biology learning instrument in a setting of cooperative learning model type STAD on human nervous system materials for junior high school. The development process of the learning device utilized a modified 4-D model which includes four stages, namely: (a) the defining phase, includes: (1) analysis of a preliminary and final, (2) analysis of students, (3) analysis of material and (4) analysis of the task; (b) the design phase, includes: (1) test preparation, (2) media selection, (3) format selection, and (4) prototype development; (c) the development phase, includes: (1) content validation performed by experts and practitioners in the field of education, (2) Field testing of learning device prototype that has been prepared; and (d) the dissemination phase. The quality of the developed learning device are as follows: 1) Lesson Plan, Student Activity Sheet, and the test  document are in valid category; 2) Practical, because the result of learning implementation observation by the observers showed that the learning device had been implemented properly; 3) effective, because the learning device satisfied the four criteria of learning device effectiveness which include: student's activity is in accordance with the tolerated time interval, teachers’ ability to manage the learning are in the very good category, students’ responded positively to the learning device and enforceability of learning activities, and students’ learning achievement has reached high category.
